You may recall that Clint and I visited the Gus Engeling Wildlife Management Area last spring (Late Winter in the Savannahs and Bottomlands) and had all good intentions of returning to this Anderson County location during the summer. After all, it is a place with velvety-black eastern coachwhips, the occasional box turtle, plenty of five-lined skinks, and it has its share of copperheads and cottonmouths. What could be better? However, I missed traveling to this spot except for a brief visit with Carl Franklin on September 29 where we were able to photograph a very nice cottonmouth.
Now that winter is approaching, we have had some cold weather, and the leaves are dropping from the trees in the bottomlands at Gus Engeling, my thoughts turn to salamanders. And so yesterday, Viviana Ricardez and I rolled the dice (and a few logs) to see if we might spot a salamander or two.
According to the Texas Amphibians field guide (Tipton, et al., 2012), The western part of Anderson County should be within the range of the small-mouthed salamander, the eastern tiger salamander, and the dwarf salamander, and we’d be within rock-throwing range of at least one more, the marbled salamander. Because of the extraordinarily wet autumn this season (you may recall the record rainfall and flooding in north and central Texas within the past two months), it seemed possible that some salamander breeding might already have taken place and there could be larvae in some of the pools. Low places that temporarily fill with water are great for amphibian breeding because they don’t have fish that would eat the eggs and larvae. In any case, a visit to this patch of the Post Oak Savannah ecoregion on a fine late autumn day seemed like a great idea.
Viviana is a veteran of lots of turtle field work, though she is ready to see any herp species that come her way. She told me of a trip to Pennsylvania during which she saw several salamander species, including our biggest, baddest, most wonderful salamander, the hellbender. We could not possibly top that on this walk, but we would have fun seeing what we could find.
We sampled several pools, pulling a dip net across the bottom and investigating the leaves, twigs, and whatever critters it might catch. Larval salamanders would look a little like tadpoles, but longer and with a feathery frill of external gills behind the head. Late in their development they would have the four small legs typical of the salamanders of the genera Ambystoma (small-mouthed and tiger salamanders as well as others) or Eurycea (including the dwarf salamander). Instead, what we found in the dip net included a few freshwater shrimp a some tiny juvenile crayfish.
We also visited some upland areas, and one beautiful pond that, as Viviana pointed out, had few snags for turtles to pull out on and bask. Otherwise, it was a delightful spot that should harbor all kinds of herps. I won’t say that Viviana is single-minded in her devotion to turtles, but if she was a character in Game of Thrones, she would be known as the Mother of Turtles. In fact, some do call her that!
We walked through a patch of cut and burned land that Texas Parks & Wildlife Department is attempting to restore to the savannah that was once typical in this part of Texas. Some native grasses are attempting to come back, although the shrubby growth that swallows up parts of the WMA are trying their best to reclaim this spot. Before this part of Texas was tamed, periodic fires helped keep the woody plants down and helped grasses dominate the spaces between the trees. Small, prescribed fires are the best friend this patch of habitat could have.
We returned to the bottomlands, and as we walked the sand and clay road toward a tributary of Catfish Creek, there was Old Man Turtle, to greet Viviana. The old man was a red-eared slider, with the typical pattern of greens and yellows now gone and replaced by dark pigment. Old male sliders often become melanistic in this way, with the carapace (upper shell) a sort of charcoal or vaguely olive-gray color with black borders of the scutes of the carapace. The head, neck, and limbs similarly darken, with the thin green lines breaking up into dots and dashes of darker and lighter gray or olive.
Viviana, of course, spotted him first, and she picked him up to examine the details of his shell and pattern. There was a notch, an old injury, on his marginals just a little to the right of center near his neck. There were subtle but lovely shades of yellow darkening to gray on his forelimbs and parts of the shell.
His response might have been, “Good day, Khaleesi – to what do I owe the honor of your examining me?” Truly, you would think that this would be the only fitting response to Viviana’s joy and respect when she handles any of these turtles. However, he was not thrilled with being interrupted in his walk to the nearby creek tributary, and his opened mouth was not exactly a grin.
After a series of photos of this delightful old turtle, we let him finish his trek across the road, plunging into the creek and immediately vanishing into the dark water. We were grateful to make his acquaintance, and happy to see him return to his watery domain as a free turtle.
We did not find salamanders, but we got to walk through some wonderful autumn woodlands and savannah, and meet Old Man Turtle of Catfish Creek!
